May 2012 The IKEv2 Protocol Specified in the IETF document RFC5996 for KMP for IPsec Key management between peers Exchange of secure identities 4 packet session key establishment SIGMA compliant Multiple authentication methods Shared secrets Public Keys (either certificates or raw keys) EAP Secure password methods Tero Kivinen, AuthenTec

The IKEv2 Protocol Flow May 2012 Initiator Responder HDR, SAi1, KEi, Ni → ← HDR, SAr1, KEr, Nr HDR, SK{IDi, AUTH, SAi2, TSi, TSr} → ← HDR, SK{IDr, AUTH, SAr2, TSi, TSr} HDR = Header SAi1, SAr1, SAi2, SAr2 = Security Association Payloads KEi, KEr = Key Exchange Payloads Ni, Nr = Nonce Payloads IDi, IDr = Identification Payloads AUTH = Authentication Payloads TSi, TSr = Traffic Selector Payloads Tero Kivinen, AuthenTec

Profile and Additions to IKEv2 May 2012 Profile and Additions to IKEv2 Need to add group key distribution Need to define what kind of Traffic selectors are used any ↔ any? Specify which features are not needed NAT-T Cookie exchange Tero Kivinen, AuthenTec

Use Cases for IKEv2 Use Cases May 2012 Use Cases for IKEv2 Use Cases Most likely in devices which already need strong cryptographic operations (Diffie- Hellman, Public Key operations) and need to have those on hardware anyways Devices which can share KMP for all layers MAC, IP, and where application layer can use IPsec as IP layer protection (for example core) Tero Kivinen, AuthenTec
